The 2023 phase of Baltimore’s long-term rebuild, which culminated Thursday night in a division title, included the off-season signing of free agent Adam Frazier and the late June call-up of rookie Jordan Westburg. The two Mississippi State alumni made solid contributions as the Orioles, predicted to finish near the bottom of the American League East, won their first division title since 2014 — back in the Buck Showalter era — by beating Boston 2-0 at Camden Yards. The young Orioles also clinched home-field advantage throughout the AL playoffs. Westburg, a 2020 first-round pick who started at second base Thursday, is batting .259 with 21 extra-base hits, 23 RBIs and 25 runs in 65 games. He was raking in Triple-A when the O’s brought him up. Frazier, an eight-year veteran signed for $8 million for 2023, pinch hit for Westburg in the eighth inning, walked and scored the big second run. The lefty-hitting Frazier is hitting .242 with 13 homers, 60 RBIs, 59 runs and 11 steals in 138 games. Both also made numerous highlight-reel plays on defense at various positions. Two years after losing 100 games, the Orioles celebrated their 100th win in a raucous clubhouse Thursday. “Pretty damn awesome,” Frazier said in an mlb.com article. P.S. In Atlanta, the Braves whipped the Chicago Cubs for the third straight night and clinched home field through the World Series, should they get there. Ex-DeSoto Central High standout Austin Riley went 3-for-4 — single, double and triple — and scored three times in the Braves’ 5-3 win. Now hitting .282, Riley has 116 runs, third on the team and fifth in the National League. The fading Cubs, in a 6-13 skid, fell to fourth in the NL wild card standings, a half-game behind Miami; the Marlins’ game against the New York Mets was suspended (until Monday?) with Miami leading 2-1 in the ninth. … In the AL West, where nothing is settled, third-place Seattle walked off division-leader Texas 3-2 on a clutch knock by J.P. Crawford; Mississippi Braves alum Dylan Moore scored the winning run in the ninth. The Mariners are 3 games back of the Rangers in the division and 1 game back of Houston in both the division and the AL wild card race. The Astros are third in the wild card standings — a game back of Toronto — and will throw J.P. France (11-6, 3.83), the rookie out of MSU, in tonight’s game at Arizona, which will start Cy Young candidate Zac Gallen (17-8, 3.49). The Diamondbacks are second in the NL wild card standings, just ahead of the Marlins and Cubs. … A pair of former first-round draftees out of MSU faced off — sorta — in the inconsequential St. Louis-Milwaukee game. Ethan Small (28th overall pick, 2019) notched his first MLB save in his fourth appearance over two years as the playoff-bound Brewers beat the also-ran Cardinals 3-0. St. Louis starter Dakota Hudson (34th overall, 2016) allowed all three runs in five innings of work to fall to 6-3, 4.98, this season.
